Core Tip
Core Tip: Neuromonitoring in critically ill patients is challenging as many patients are unfit for invasive intracranial pressure (ICP) monitoring or unstable to transport for imaging. Bedside ultrasonography based optic nerve sheath diameter (ONSD) has been proven to be a reliable option in patients with traumatic brain injury (TBI). However, it’s efficacy has not been extensively evaluated in neuro-medical patients. In this review, we analyzed data from 37 articles which had compared ONSD with other established modalities of measuring ICP in non-TBI patients. The analyzed data suggests that ONSD may be a useful tool to detect raised ICP and predict outcome in patients with acute ischemic stroke, intracerebral bleed and intracranial infection. However, further large-scale randomized trials are required, especially in patients with septic metabolic encephalopathy, dysnatremias and aneurysmal subarachnoid hemorrhage, before it is routinely employed in managing neuro-medical patients with elevated ICP.
